Rhabdoid Meningioma In A Background Of Atypical Meningioma With Lipomatous Metaplasia: Case Report And Review Of Literature
Meningiomas are heterogenous in their histology, and most of histologic subtypes have no prognostic significance, and are classified as WHO grade 1. Those with clinically increased risk of recurrence are classified as WHO grade II or III. A relatively recent addition to the meningioma family is a rare variant called rhabdoid meningioma, which is associated with increased risk of recurrence and aggressive clinical behavior and therefore classified as WHO grade III meningioma. We report a case of rhabdoid meningioma in a 43 year old man, which exhibited an unusual combination of rhabdoid and lipomatous components, in a background of atypical meningioma. The clinical features, neuroimaging, surgical treatment results and pathological features of this case are described with a limited review of literature regarding prognosis of patients and treatment options.
